Convert transaction constants to i18n-compatible getter functions

- Convert all hardcoded constant arrays to functions accepting TFunction
- Add transaction.constants namespace with 40+ translation keys
- Update contant.ts: All exports now use get* prefix (e.g., getCashReceiptPurposeTypeBtnGroup)
- Replace ko/en properties with single name property using t() function

Updated constants:
- getAllTransactionMoidTidOptionsGroup(t)
- getAllTransactionStatusCodeBtnGroup(t)
- getAllTransactionServiceCodeOptionsGroup(t)
- getAllTransactionStatusCode(t)
- getCashReceiptPurposeTypeBtnGroup(t)
- getCashReceiptTransactionTypeBtnGroup(t)
- getCashReceiptProcessResultBtnGroup(t)
- getEscrowSearchTypeOptionsGroup(t)
- getEscrowDeliveryStatusBtnGroup(t)
- getEscrowSettlementStatusBtnGroup(t)
- getBillingSearchTypeOptionsGroup(t)
- getBillingRequestStatusBtnGroup(t)
- getBillingProcessResultBtnGroup(t)
- getBillingPaymentMethodBtnGroup(t)

Updated components (9 files):
- Filter components: all-transaction, cash-receipt, billing, escrow
- List pages: billing, cash-receipt, escrow
- UI components: list-item, important-info-section

All constants now properly support Korean/English language switching.
